A 25 GHz 32 b integer-execution core in 130 nm dual-V/sub T/ CMOS

A 32 b integer execution core implements 12 instructions. Circuit and body bias techniques together increase the core clock frequency to 5 GHz. In a 130 nm six-metal dual-V/sub T/ CMOS process, the 2.3 mm/sup 2/ prototype contains 160 k transistors, with RF-ALU units dissipating 515 mW at 1.6 V.
